I want to be that 80+ guy still going out camping. Neither father nor father in law lived that many years, so I hope to break the cycle.

Right? Hell, I’ll consider 60 a win.
The avg age of both my parents and now including my wife”s lives is 59 and change.
At 83 if I was still campin I’d take a bad loan out on a new TC with the biggest air conditioner if I had to. Prolly ain’t gotta worry about paying it off and wouldn’t have to suffer with a table fan in the sweltering heat….

The problem with those portable a/c units is this:
They blow hot air to the outside of the RV. That exhaust air needs to be replaced with and equal amount of outside air coming into the camper, so the A/C is fighting a never ending battle of trying to cool the air it's drawing in from the outside (through an open roof vent or window) to replace the air it's shooting out through its exhaust hose.

Twin hose model solves that problem as described in an earlier post, quoted below:

If you do go with a "portable", look for one with twin hoses. the single hose models, use already cooled interior air to cool the condensor and then dump it outside, along with all the cooled air. This drastically reduces the effective cooling power (regardless of the btu listed). The twin hose style pulls in outside air to cool the condensor and then sends it out the other hose making it far more effective.

THIS is a neat unit that I have been looking at. It's 12V and it's a heat pump so it replaces both your furnace and gives you an ac and draws just over 11 amps on full load. Best of all compared to other 12V AC's it's a little more affordable, but it would take a bit of work to install.


The link you provided goes to a 115v (per the website) unit.

Also, heat pumps are not great with actual cold temps. 40-50F, they do pretty well. By the time you get into the 20'sF, they lose a lot of heating power.

For the price of this unit, probably cheaper to get a standard RV roof mounted unit.

So it is, I missed that sorry, as for cold weather performance.. this one doesn't give spects so ya it most likely sucks, but lots can go down to -30C now days, they just cost a little more.. but seeing as this one is 120V its no good anyways.. weird as the link I followed was a 12V so I'll have to check that out and see if it switched me.

Our windows are crank-out jalousies with attached interior screens so using a window is out of the question: we do not want to remove the whole window unit for a retro. The issue of draining the moisture from the A/C won't work with the window. Perhaps a bucket with a cover that has been cut for a hole to fit the drain hose. This works for us to drain gray water out to an enclosed bucket when necessary. We also have a portable dehumidifier but it is ineffective.

Modern portable ACs don't need to be drained very often if at all. The moisture is vaporized and sent out the exhaust tube.

I drained mine a sum total of TWICE in all the years I owned it.

You do you, though.
